Interface TokenAuthenticationService

All Superinterfaces:

Serializable

All Known Implementing Classes:

TokenAuthenticationServiceImpl

public interface TokenAuthenticationService
extends Serializable

Service to manage generation and storage of authentication tokens. Each token must be unique and persisted in the back-end with the user information it is bound to: user name, application name, device name, device description, permission.

Typically, the service is called by the TokenAuthenticationServlet to get a token from the user information passed as request parameters, and it allows the TokenAuthenticator to check for a valid identity given a token passed as a request header.
